Expert review for SendGrid integrations built with Supermaven. We fix Supermaven-generated SendGrid code for security, error handling & production readiness. From $19.
Common Supermaven issues affecting integrations
Fast completions accepted without review introduce subtle type errors
Supermaven's speed is its core advantage, but it encourages accepting completions quickly. TypeScript type errors, incorrect function signatures, and wrong argument orders frequently slip through when developers tab-accept completions at high speed.
Security-sensitive code patterns completed without security review
In security-critical code paths like authentication, token validation, and database queries, Supermaven's completions can introduce subtle vulnerabilities — such as completing a SQL query without parameterization or missing a signature verification step.
Existing codebase anti-patterns replicated across new files at high velocity
Supermaven learns from your codebase, which means bad patterns — deprecated APIs, insecure functions, or architectural mistakes — get propagated to new code rapidly due to how quickly completions are accepted.
SendGrid issues we find in Supermaven apps
Using deprecated v2 Mail Send API
AI tools generate code using the SendGrid v2 API endpoint and format instead of the current v3 Mail Send API, missing features and facing eventual deprecation.
Sender authentication not configured
Generated code sends from addresses without domain authentication (SPF/DKIM), causing emails to fail or be marked as spam by receiving mail servers.
API key has full access instead of restricted permissions
AI tools create and use API keys with full admin access when only Mail Send permission is needed, creating an unnecessary security risk if the key leaks.

Frequently asked questions
Can you review my Supermaven-built SendGrid integration?
Yes. We regularly audit SendGrid integrations in Supermaven-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What SendGrid issues does Supermaven typically create?
Common issues in Supermaven-generated SendGrid code include: using deprecated v2 mail send api, sender authentication not configured, api key has full access instead of restricted permissions. We fix all of these in our code review.
How much does it cost to fix my SendGrid integration?
Start with our code audit ($19) to get a complete list of SendGrid issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What SendGrid best practices does Supermaven typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for SendGrid. Our review checks all of these and provides specific fixes.
